Then you file to change who can claim the exemptions for the children.
However, if he is one of those scofflaws who is not filing a tax return because his money is offshore, you might be able to go ahead and claim all 4 children, because under the federal tax code you are the only one allowed to claim the children. Its the state court judge you have to worry about.
However, you would also need to make sure that it really gives you a significant benefit to claim all 4 children.
